To @il wioffn 'it may conce/m.'

Be it known that l, ANDREW ll'orieseef. of littsburg, Allegheny county,Penneylvanie, lleve invented e new and useful Method' of RollingTile-Plates, of which the following is e full, eleer, and exeolydescription, reference being had to the accompanying drawings, lformingpart of this speeiiieatien, iii Wliieli Figure l is a. from. elevationol e tliree-liigl1 rolling millliaving e series of passes suitable i'for carrying out my invention and showing; She different steps oi theoperation; Fig. 2'is Similar View showing the final or iinisliiiig 5 andFig'. 3 is u sectional View showing the completed tie plete.

2. The method of rolling tie late bers .serving right-angledlongitudinalyextending middle end lateral :i enges, which consists infirst passing o reotengnlnr billet through nn'iriitielpess in diagonalposition to form rudimentary ilnnge portions, Working two oppositecorner portions of the bei' into a. middle allonge and the other Itwocorners the lateral flanges, ond subseuently rolling the shape to reduceand s such 'lel'iges; substantially es deseri 3. The herein describedmethod of rolling longitudinally flanged tie plete bers, Wl'xiehconsists in iii-st sininlteneonslyreducing the rectoz-ignler billet toform o bo .y portion with four rudimentary flanges, then rollingI theber in :successive passes to reduce :mi shape its body portion 'andthree of seid fienves, and et the seme time `remove the onrti flange byrolling it into the body of the bnr; substantially :is described.

The method of rolling tie plete bers and longitudinelly extending middleand. lateral 'lenges which project et substantially right ongles to `thebody portion, .Whieh consists in first passing o rectangular billetthrough en initial pass in dingo-nel position to forni rudimentaryflange portions from the corner portions of the rectangular billet,Working two opposite rudimentary flange portions oi the ber into thebody portion and into :i middle flange end the other 'two rudimentary'flange por# tions 'into 'the lateral flanges, and subse nently rollingthe shape to reduce and Snape suoli iienges end to reduce and shoulderthe body portion of the tie plate; snbstsntielly es described.

then rolling in s series of subsequent passes to remove said bum s andtemporary encge by rolling the metaJ thereof into the bo portion andinto the other ang'es, end at the same time reducing and shaping thebody portion of the other flanges into fine] angular llustngjels'1substantially as described. i

, 7. The herein described method of rolling tie plete bars havinglonefitudinelly-extend-l ing lateral flanges, Whiei consists in firstforming e shape heving rudimentary lateral flanges, and then rollingseid shape 1n a pass in which the lateral flanges are'moved bodilyinward by lateral pressure against their outer sides towards each other;substantially as described.

8. ,T he herein described method oi rolling' tie plate bers having lonitudinnlly-extending lateral flanges, Whic consists in first forming ashape having rudimentary lateral {lon-ges et its edges, and then pessinrseid shape through a pass in which seid enges are moved bodily inwardtowerds each other by lateral Apressure against their outer sides, andat the seme time the -metal is forced laterally outwardy in the plane oithe body portion beyond seid flanges by vertical rossore on seid bodyportion; sublstentiolly es described. l
